I'm not sure how any of this time-wimeyness works without the Moment still putting a time lock on the war and destroying all remnants of the Daleks and Time Lords outside of Gallifrey (with post-last-day Gallifrey stuck in a pocket universe outside the time lock). Otherwise, you're left with the the Doctor being able to just go back to earlier Gallifrey and pick up his friends and family at any point.
I don't think the Moment removed the time lock; it just allowed the Doctors to penetrate it at that particular, err, moment. Not tearing down the wall so much as creating temporary openings in it.
Again, I'm fairly sure Moffat's intent is that the Moment didn't change anything, that this is what happened all along. For narrative reasons, that's the most likely interpretation, because it would render the events of the past eight years' worth of stories irrelevant if history had really been changed in any major way. (Sure, Moffat's cracks in time undid some historical events, but nothing involving the Doctor's own personal journey, which is the important thing here.) So it can reasonably be assumed that everything that was true before about the Time War is still true,
except for the interpretation of what happened to Gallifrey at its very conclusion.
